CVE-2026-25873
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOmniGen2-RL contains an unauthenticated remote code execution vulnerability in the reward server component that allows remote attackers to execute arbitrary commands by sending malicious HTTP POST requests. Attackers can exploit insecure pickle deserialization of request bodies to achieve code execution on the host system running the exposed service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOmniGen2-RL's reward server component has an unauthenticated remote code execution vulnerability. Attackers can send malicious HTTP POST requests containing specially crafted pickle-serialized data that, when deserialized by the server, allows arbitrary command execution on the host system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if OmniGen2-RL is installedSearch for OmniGen2-RL related files, packages, or directories in common installation locations. Use commands like 'pip list | grep -i omni' or 'find / -name "*omnigen*" 2>/dev/null' to locate the software.Affected if OmniGen2-RL software is found in the environment
-
Locate running reward server processesRun 'ps aux | grep -i reward' or 'netstat -tlnp | grep -E "(port|8080|5000|8000)"' to find the reward server component actively listening for HTTP connections.Affected if A reward server process is running and accepting HTTP connections on a network port
-
Inspect reward server code for pickle deserializationExamine the reward server source code for usage of 'pickle.load()', 'pickle.loads()', or 'cPickile.load()' on incoming request data. Search for patterns like 'pickle.load(request.body)' or similar deserialization of HTTP POST content.Affected if The code uses pickle to deserialize request bodies from HTTP POST requests without validation
-
Check if authentication is disabled on the endpointReview the reward server configuration and code to determine if the HTTP endpoint implements any authentication or authorization checks before processing request data.Affected if The reward server accepts requests without requiring authentication (the vulnerability is specifically unauthenticated RCE)
-
Compare installed version to any known affected versionsIf a version number is discoverable (via 'pip show omnigen2-rl' or examining version files), compare it against the affected version range provided by the CVE.Affected if The installed version falls within an affected range specified by the CVE
A user is affected if OmniGen2-RL is installed with the reward server running, the code uses pickle to deserialize unauthenticated HTTP POST request bodies, and the server is network-accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately restrict network access to the reward server and disable it if not required. If the service is needed, implement authentication and replace insecure pickle deserialization with secure formats like JSON, or use a safe unpickler library with allowlist verification.
